Denver Broncos linebacker Spencer Larsen will miss a few weeks after injuring his shoulder in a fall in the locker room at Cincinnati.

Coach Josh McDaniels said Monday that Larsen slipped on a slick surface and injured a shoulder while trying to break his fall.

McDaniels said Larsen's tumble wasn't the result of horseplay.

The second-year pro's injury apparently occurred in the 90 minutes before kickoff because he wasn't among the inactive players in Denver's 12-7 win over the Bengals.
